A cold windy nor’easter day, so what better opportunity to go through and revamp the HyperGlossary entry on hazard classification to align with HCS 2024 changes. https://www.ilpi.com/msds/ref/hazardclassification.html

Some key updates:

1. Redefined the definition flow by introducing “hazard class” and “hazard category”, followed by “hazard classification” and adding a diagram that shows generally and specifically how the first two generate the last one.

2. Added notes about the interplay between HCS and GHS revisions.

3. Converted the two bullet lists of health and physical hazards into much more readable tables that now include links directly to the hazard classes in Appendices A and B of the HazCom Standard.

4. Two new additions to the physical hazards along with about eight edits to include new requirements and few prior omissions.

5. Clarified the discussion on mixtures a bit.

6. Added a couple new resources in the Further Reading list - including a nice 384 page document from OHSA on Hazard Classification Guidance for Manufacturers, Importers, and Employees which is full of detailed information, references, decision-making rationale and more.

And, of course, as with all these updates, the dictionary for the Safety Demystifier will mark up the new terms: https://www.ilpi.com/msds/ref/demystify.html
